Patent CA-2381472-A1 (CA)
Inventor: FUJIMAKI MAKOTO
IPC: G02B6/02
Filed: 2002-04-11
Abstract: An optical waveguide grating is formed in an optical waveguide core and/or in an optical waveguide cladding where an electric field of light propagating in the core is spreading by implanting accelerated ions through a mask to the optical waveguide. The mask has enough thickness to prevent the ions irradiated to the masked parts from reaching the portion where the grating is formed. The acceleration energy of the ions is chosen to make the lateral straggling of the implanted ions in the optical waveguide less than three fourths of the period of the grating, or the acceleration energy is chosen to make all or a part of the implanted ions pass through the portion where the grating is formed.

Abstract: A method and system using Radio Frequency Identification (RFID) technology to support the issuance of targeted purchasing incentives to retail customers and supporting marketing analysis. RFID technology is used to determine the current purchase selections of a retail customer and targeted marketing incentives are given to the customer based on the current customer purchase selections either alone or in combination with prior purchase history.  Customer purchase selections can be determined at various points through out the store and targeted incentives provided during the shopping visit. The current purchase selections can be optionally added to a data base for future use in selecting directed incentives or analyzing purchasing patterns to support development of marketing strategies. RFID technology, as well as other techniques, may be used to identify the customer and allow the customer's identification to be stored into the purchasing database either in association with purchase selections or to record a customer's visit to the retail establishment.

Title: A method for regulating gene expression
Inventor: OKAMOTO HITOSHI
IPC: C07D311/10
Filed: 2002-04-22
Abstract: A target gene can be expressed site-specifically and with desired timing without damaging the cell itself or inducing mutation in a nucleic acid molecule within the cell. Expression of the above target gene is suppressed by allowing a caging agent represented by the following formula (1) to bind to a nucleic acid molecule containing the target gene; and the suppression of expression of the above target gene is cancelled by detaching the caging agent from the above nucleic acid molecule by UV-illumination.

Abstract: A system for monitoring carbon monoxide in an environment which includes an apparatus emitting carbon monoxide, such as an internal combustion engine. A  carbon monoxide sensor measures a concentration of carbon monoxide in the environment and provides an electrical signal to a processor that is representative of the measured concentration of carbon monoxide. The process or determines the concentration of carbon monoxide corresponding to the electrical signal, provides an output signal at or above predetermined carbo n monoxide concentration thresholds, calculates an estimated carboxyhemoglobin  level for the operator corresponding to the carbon monoxide concentrations calculated over time, and provides an output signal at or above predetermine d carboxyhemoglobin thresholds. The signals are then received by one or more devices which provide textual, visual, and/or audible warnings indicating th at environmental concentrations of carbon monoxide have caused a predetermined warning threshold to be met or exceeded. The signals may also be received by  a device which shuts down the carbon monoxide generating apparatus.

Filed: 2002-06-12
Abstract: This invention is a method for nondestructively determining the deterioration of determining ferromagnetic materials by quantifying the change in brittleness with aging of the materials. This invention supposes acquirement of an embrittlement coefficient b by measuring a magnetic susceptibility .CHI. b of ferromagnetic materials under a magnetic field having a specified intensity H.  And the coefficient b of the ferromagnetic materials is calculated by putting the intensity H and the susceptibility .CHI. b into an equation: b = .CHI.b H2. By the coefficient b, a correlation between the coefficient b and a referenced embrittlement factor of materials like said determining materials is obtained previously. Said coefficient b of said determining materials in the initial and the deteriorated states is acquired. The factor corresponding to the coefficient b is obtained from the correlation. It is possible to quantify the change by comparing the values of the factor in the initial and deteriorated states.

Inventor: LYZNIK LESZEK ALEXANDER
IPC: C12N15/82
Filed: 2001-09-14
Abstract: Compositions and methods for targeted genetic manipulation of an organism are provided. The compositions are novel integration vectors derived from the Mu bacteriophage comprising an active cleaved donor complex (CDC) and further comprising a targeting mechanism whereby integration of the Mu transposable cassette may be directed to a predetermined target site within a host organism's genome. These integration vectors comprise a Mu transposable cassette and one or more navigator elements that direct targeted insertion of the CDC. Methods of the invention utilize the integration vectors of the invention to insert the Mu transposable cassette into a target site of an organism's genome. The insertion occurs in the absence of the MuB accessory protein. The methods are useful for modulating activity of known genes and for targeting integration of nucleotide sequences of interest into a specific location of an organism's genome. Accordingly, the methods may also be used to create gene disruptions and knockouts.
